complex gateway integration and support

CQR payment service integration ([login to view URL]), manuals attached. The project is roughly at 60% mark, it was abandoned by 2 coders already, who proved their inhablitity/unwillingness to finish it. The project is not big in terms of number of code lines to be written, but it's a very unorthodox and demanding way of payment gateway integration, therefore only a coder with enough expertise in the area won't be stuck in the midst of it. After finishing the integration you should be able to give a continous support for at least 3 months, the payment for it will be separate from the integration. Having a fixed IP or fixed IP range ([login to view URL] - xxx being fixed) for your work connection is mandatory, you will not be able even to try out the project, if you don't fulfill this precondition.
